Electrochemistry

During 1800s, people learned that electricity caused muscles to twitch and material to change. How and why?
A. Volta (1745-1827) experimented with different materials, and made voltaic piles (batteries)
William Nicholson (1753-1815) observed bubbles forming on the surfaces of metals submerged in water when they are connected to a voltaic pile
Humphry Davy (1778-1829) observe electrolysis of water and metal salts
Michael Faraday (1791-1860) studied electrolysis, and discovered the relationship between charges and chemical stoichiometry
For an element, the mass deposits on an electrode by electrolysis is related to its atomic weight, and the total electric charge that passes through the solution
To deposit one mole of silver requires 96485.309 C of charge.
1 F = 96485.309 C
